Enderby's Wharf is a wharf and industrial site on the south bank of the Thames in southeast London, associated with Telcon and other companies. It has a history of more than 150 years of production of submarine communication cables and associated equipment, and is one of the most important sites in the history of submarine communications.

The wharf lies on the Greenwich Peninsula a little to the north of the historic centre of Greenwich between the Thames and just south of the Blackwall Tunnel approach road, across the river from Cubitt Town. It covers an area of some 16 acres (65,000 m²) and has a frontage of around 600 feet (180 m). In 2010 a proposal was made to turn 3 acres (12,000 m²) of the river frontage of the site not in use by Alcatel into a cruise liner terminal and housing. The proposal (known as 'Enderby Wharf') received planning approval in 2011, subject to approval by the Greater London Authority.

The wharf was first developed by the whaling company of Samuel Enderby & Sons, which acquired the site for a ropeworks in 1830. Enderbys also built Enderby House, which remains today as a listed building and part of the Alcatel works on the site.
